Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically a laser machine with an upward smoke blowing device. Background Technology

[0002] Laser machines generate fumes during material processing, and these fumes rise to the surface. Since the laser machine requires an unobstructed optical path to operate, the rising fumes obstruct this path. This obstruction weakens the laser beam, directly reducing its energy. Insufficient laser energy leads to poorer cutting results, or even incomplete cuts, impacting both processing quality and efficiency.

[0003] Currently, most laser cutting machines on the market have fume extraction devices on both sides of the gantry, or opposite fume extraction and air blowing ports on both sides, to draw away the smoke and dust generated during material cutting from the side. However, this side-exhaust method cannot effectively remove the rising smoke and dust, and some smoke and dust will still enter the gantry shell, affecting the laser beam path.

[0004] To address this issue, we developed a method of installing a fan device on the gantry. This device automatically senses rising dust and, when activated, pushes the dust downwards, preventing it from rising and obstructing the laser path. This ensures the laser machine's optical path remains unobstructed, preventing a decrease in laser energy due to dust blockage. Consequently, the equipment can process materials normally and efficiently, guaranteeing that the processed materials meet quality requirements. Utility Model Content

[0005] The purpose of this invention is to provide a laser machine with an upward smoke blowing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A laser machine with an upward smoke blowing device includes a main unit, on which a cutting gantry is mounted. A laser head and corresponding optical path components are mounted on the cutting gantry. A maintenance cover is hinged to the front of the cutting gantry. A downward blowing assembly is mounted on the top of the maintenance cover, located above the laser head and optical path components, for blowing air downwards. A smoke detection assembly is mounted on the maintenance cover for detecting whether there is smoke near the laser head and optical path components. When the smoke detection assembly detects smoke, the downward blowing assembly blows air downwards.

[0007] As a further preferred embodiment of this utility model: the downblowing assembly includes a plurality of fans fixedly arranged on the top of the inner side of the maintenance cover, and the top of the maintenance cover has a plurality of air inlets corresponding to the fans.

[0008] As a further preferred embodiment of this utility model: the smoke detection component is a smoke detection head, and multiple smoke detection heads are provided on the front side of the inner side of the maintenance cover.

[0009] As a further preferred embodiment of this utility model, a filter screen is provided between the fan and the air inlet.

[0010] As a further preferred embodiment of this utility model: a plurality of assembly profiles located on both sides of the air inlet are fixedly provided on the top inner side of the maintenance cover. Two slots are opened on the inner side of the assembly profiles, and the fan and the filter screen are respectively inserted into the two slots. Fastening bolts are threadedly connected to the assembly profiles, and the ends of the fastening bolts penetrate the fan and the filter screen.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This laser machine, by incorporating a downward-blowing fan on the gantry, prevents fumes from entering the gantry housing, thus avoiding the problem of fumes rising and affecting the laser beam path formed by the optical components within the gantry. Simultaneously, the fan's placement on the maintenance cover allows for simultaneous inspection and maintenance of the fume extraction device when the laser head is being inspected, facilitating assembly and maintenance. Furthermore, a filter on the fan prevents external impurities from being blown into the optical path during downward airflow, ensuring unobstructed laser beam flow. Additionally, a smoke detector design eliminates the need for continuous fan operation when cutting materials with minimal smoke; the main controller automatically activates the fan to blow downwards when smoke is detected, saving energy. The design is scientifically sound, practical, and highly functional. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0015] Please see Figure 1-8 This embodiment provides a laser machine with an upward smoke blowing device, including a main platform 1, a cutting gantry 2 mounted on the main platform 1, a laser head 13 mounted on the cutting gantry 2, and corresponding optical path components. A maintenance cover 3 is hinged to the front of the cutting gantry 2. The above structure is a common structure of conventional laser cutting machines familiar to those skilled in the art. The optical path components are the components that constitute the optical path system in the laser machine, including laser tubes, reflector frames, etc. The optical path components transmit the light to the laser head 13, which then emits light to perform laser cutting on the material on the main platform 1. This is common knowledge familiar to those skilled in the art and will not be further elaborated upon.

[0016] In practical applications, when cutting certain materials, a large amount of smoke is generated due to the material's inherent properties. To prevent this smoke from rising into the upper cutting gantry 2 and affecting the optical path, and to ensure the smooth flow of the laser beam, a downward-blowing assembly is installed on the top of the maintenance cover 3, located above the laser head 13 and the optical path components, for blowing air downwards. Figure 1-7 As shown, the down-blowing assembly includes multiple fans 4 fixedly arranged on the top inner side of the inspection cover 3, and multiple air inlets 9 corresponding to the fans 4 are opened on the top of the inspection cover 3. In order to prevent smoke or other impurities in the outside air from being blown into the cutting gantry 2 by the fans 4 and affecting the internal laser beam path, a filter screen 5 is provided between the fans 4 and the air inlets 9.

[0017] Meanwhile, to facilitate regular maintenance and cleaning of the fan 4 and filter 5, multiple assembly profiles 6 are fixedly installed on the top inner side of the maintenance cover 3, located on both sides of the air inlet 9. Two slots 10 are formed inside the assembly profiles 6, and the fan 4 and filter 5 are respectively inserted into the two slots 10. Fastening bolts 7 are threaded onto the assembly profiles 6, with the ends of the fastening bolts 7 penetrating through the fan 4 and filter 5. It should be noted that the fastening bolts 7 are a conventional design familiar to those skilled in the art; simply creating corresponding threaded holes on the assembly profiles 6 and corresponding through holes or threaded holes corresponding to the fastening bolts 7 on the sides of the fan 4 and filter 5 is sufficient. This is common knowledge and will not be elaborated further. The installation of the assembly profiles 6 on the maintenance cover 3 is also a conventional design familiar to those skilled in the art, and can be achieved through welding, screw fixing, etc. Preferably, as... Figure 2 and Figure 5 As shown, by integrating a protruding fixing plate 11 on the side of the assembly profile 6, and fixing the fixing plate 11 to the maintenance cover 3 by fixing screws 12, the assembly profile 6 can be fixed on the maintenance cover 3. This is a conventional design, and this application will not elaborate further.

[0018] Additionally, a smoke detection component is installed on the inspection cover 3 to detect whether there is smoke near the laser head 13 and optical path components. When the smoke detection component detects smoke, the downward blowing component blows air downwards. This is a standard design, such as... Figure 3 , Figure 6 as well as Figure 7 As shown, the smoke detection assembly is preferably a smoke detection head 8. Multiple smoke detection heads 8 are arranged inside the front side of the inspection cover 3, enabling them to detect smoke near the entire optical path system. This is common knowledge familiar to those skilled in the art, such as... Figure 3 , Figure 4 as well as Figure 6 As shown, the smoke detector 8 should be positioned at the lower end of the maintenance cover 3 so that it can be detected in time when smoke is about to float into the cutting gantry 2, and the fan 4 can be controlled to blow downward to prevent the smoke from entering the cutting gantry 2.

[0019] It should be noted that, as is common knowledge familiar to those skilled in the art, both fan 4 and smoke detector 8 should be connected to the main controller on the main unit 1, and their coordination and operation should be controlled by the main controller. The main controller has a conventional structure, as shown below. Figure 1 , Figure 8 As shown in the lower right corner of the upper surface of the main unit 1, this application will not repeat the details.

[0020] When cutting materials that produce a small amount of smoke, most of the smoke can be sucked away by the fume extraction pipes on the side or bottom of the cutting machine. A small amount of residual smoke and dust rises to the lower end of the inspection cover 3, near the laser head 13, and is detected by the smoke detector 8. The smoke detector 8 transmits the detection signal to the main controller, which then controls the fan 4 to operate, blowing downwards to dissipate the smoke. When cutting materials that produce a large amount of smoke, the main controller simply controls the fan 4 to continuously blow downwards; this is a standard operation familiar to those skilled in the art and will not be described further.

[0021] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application. Solutions or features that are prior art or common knowledge to those skilled in the art will not be described in detail in the above embodiments.

[0022] Furthermore, the technical solutions of this application are not limited to the above embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
